Does anyone remember Eco Mode on the Optimus G? As far as I know, when it's activated, the APQ8064 (4xKrait 200 + Adreno 320) runs like a MSM8960T (2xKrait 200 + Adreno 320), shutting off two cores. People said that it made a large impact on battery life but performance was more or less unaffected (probably offloads more rendering to the GPU).
I saw in this thread that the OP managed to add Eco Mode to the ATT stock ROM but it says "WIP - doesn't show UP" of which I have no clue what it's supposed to mean.
the changelog says WIP for v1 alpha but for v2 and v3 it doesn't make any mention of it. Has anyone tried out the mod?
Interesting. The battery saver I this phone is useless, this world be great.
Typically unless am added feature it's mentioned as being reduced it should still be there.
I'm going to think that while it's chimed into the system.ui there's no switch to activate it. Possible a needed app.
ECO Mode on the OG did not turn off 2 cores. It just significantly throttled the way the cpu ramped up to higher frequency.

Really? I heard reports of it either shutting 2 cores or changer governor to conservative or something
I run ECO mode quite often. Governor stays the same. It just spends more time at 594mhz as its intermediary frequency than 1134mhz. It also hits max frequency sparingly.
You can see the difference in cpuspy or even using CPU-Z real time core frequencies. Shows you what each core is running at.

According to the System Tuner app, my CPU went up to 75 degrees Celsius while I was playing a track on Google Earth. I was running Earth for only a few minutes before it reached 75. I'm not sure if that's the peak yet...maybe it can go even higher.
I've seen several other threads about heat, but most people talk about 50s and 60s. Anyone reach 75C? The front and back of the phone, the top around the camera, were both very hot. It was almost uncomfortable to touch.
Again, I'm talking about 75 Celsius, not Fahrenheit. And I'm referring to CPU temperature according to System Tuner app, not battery temp. Anyone reach this?
picture plz.
the reason is bc someone did a stress test on the N4 and found that the device shuts down at ~57-59C (correct me if im wrong) to prevent damage to the hardware.
Edit: found the link http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
75ºC on a quad core?
I thought it was supposed to be more efficient than a dual core... 167ºF just seems like it's way hotter than any electronic device should ever be.

My first gaming laptop was an ASUS Republic of Game first generation. They did a horrible job cooling the machine. During the 2 months before the machine failed, the GPU would reaches 110 - 140 C if I played games (then, of course, the machine turned the GPU off and still ran as everything else was still about 70-80 C)
When the machine did fail, I opened it up, and found 2 fried thermal unit, a fried GPU and a nearly fried HDD) Amazingly, the machine stills runs, as long as I don't load GPU driver
Well, that's the story. Back to OP, as you see, if the temp is too high, you device can be literally fried. So if you turn off the thermal throttle, please enable it back on and do you best to keep your device cool
I tried to replicate just now and could only go up to 63c. I don't want to keep trying based on the comments here so far. If it happens again I'll be sure to get a screen shot and be aware of what's running.
Where would the thermal throttle toggle exist, if I have the capability at all? I'm running faux123 kernel and use trickster mod and trinity kernel tools for tweaking. I don't see anything about throttle control.
On a similar note, faux123 seems to default to 1ghz minimum cpu frequency. Does that seem right? I've flashed lots of kernels before on previous phones and they always default to the lowest value. When I force the setting down to 384mhz, it automatically changes back to 1024mhz the next time I go in my tool apps. Does this seem normal?

I haven't seen a Nexus 4 kernel that has thermal throttle toggle, or have it disabled yet. I am just checking if you're running one that I am not aware of

Minimum cpu frequency enforced by kernel is normal. I am not certain if faux123 default to 1 ghz min, but if it's the case, it seems weird for me too. Definitely not good for the battery. If there's no other CPU control apps, I recommend double check the settings, then find an update for faux123, or use trinity kernel
I just flashed a new kernel and my minimum cpu now seems more normal. I hopefully that alleviates the crazy temperatures too.
I'll try to test again tomorrow to see if my temps still go bonkers. It's time to sleep now. Thanks for the help, everyone.
ROM: NEAT ROM 4.4.4
KERNEL: gustavo_s' kernel for AOSP version 04 Feb 2015 with Synapse.
So one day when drinking beer I thought to myself: if Ondemand is so sensitive in jumping to higher frequencies, why bother setting the threshold low? So I just simply went to Synapse and set the up-threshold to 99%. Naively I just thought it was to make sure the CPU was full until it needed a faster frequency. To my surprise, a few days later was fantastic: the time my GS spent on high frequencies was so good it looked like I was using conservative, the least time was on 1200MHz and goes up along with lower frequencies. And the performance was intact :silly::silly::silly:
:silly::silly::silly: can anyone confirm you had tried this before?
One last thing: I just enable GPU rendering, I read that GPU used more power so it is not efficient but on this kernel I am able to use 54MHz and 66MHz which only drain 800Mah which is less than the voltage of 200MHz. My first feelinng is that scrolling through Manga app no longer lags. Will this work as I expected, guys? :silly:

Using gpu in lower frequencies may unstable phone. I use @Gustavo_s kernel too. My first frequency step is 108MHz and 800mV can easly handle this. Lower frequencies only slows phone. Enabling gpu rendering also causes overheating on AOSP roms on i9100 belive me I tested.
Edit: Also 99 is a high value. 85 to 95 is ok.
Sorry for my bad english too..

Yeah I may feel that right, I'm switching to 66Mhz and it feels better, yet I don't think GPU rendering causes overheating, it felt the same, I'm turning it off for comparison a few days... :silly:

I assume you don't care about gaming performance or any graphics intensive tasks? Don't see why this is a weird tweak, but it is still a noteworthy tweak that may help people who want raw computing speed but no gaming.

That's right, don't have any single game, but I'm very very into multi-task. Switching from app to app in seconds... so that obviously works for multi-task people.
I recently switched to intellidemand with the same setting and notice the CPU spent even less time on the high frequency, but it begin to has lag so I think ondemand is still my best choice right now
So I usually use CPUSpy to monitor my CPU usage. This comes in handy once the device is rooted and I can see how custom kernels and settings affect battery life and cpu cycles. My LG G4 is the tmobile variant and obviously not currently rooted. I notice through CPUSpy that my cpu speed literally never exceeds 1440mhz.
I don't have any problems with that per say, everything on the device still runs buttery smooth without anything more than the occasional hiccup or lag. I'm curious if anyone else has monitored their CPU speeds and noticed the same thing? I just find it a little interesting.
CPU spy can't even see the A57 cores so there's no way it can see what speed it's running at.
4 cores are limited to 1.44 the rest are 1.8
I have not used CPUSpy. But CPU-Z will show you the speed of each of the 6 cores. As mentioned, the last 2 are the only ones I've seen reach 1.8GHz, the first 4 seem to top out at 1.4 GHz.
Ok.. Using cpu-z..
That's how mine looks "at rest". When it's sitting quietly, saving the battery. Crank up some apps, and you should see those clock speeds rise.
But, trying to improve my battery life, and keep the temps down, I've been hoping to see those numbers stay low, not actually show how high they can go
I agree.. As ive stated, the device runs great i just found it odd. It even calls it a 1.44ghz cpu in the cpu profile and mostly no matter how hard i push the device i cant break that speed
Right as CPU-Z opens, the clock speeds spiked briefly. I was able to get a screenshot quickly.
Do yours also jump up for a second or two right as the app opens?
This has been discussed already. As the previous post shows, they do get to 1.8Ghz when required.
Hey. After checking CPU on "Kernel Adiutor", I noticed that none of six cores are going offline. All of them is staying online, its happening also if there is no tasks on background. I am using interactive governor for both big and LITTLE cores. I want to know, is there better governor, that will not sacrifice performance, but will put some cores to offline mode, so battery life would be better. Any suggestions for hexacore governors?
Thanks!
EDITED on 28.11.15:
Thanks dark4codrutz for explaining things! So I have flashed v4tk kernel version 5 for XT1572.
Settings at "Kernel Adiutor":
CPU
big cores: min - 384 MHz, max - 1824 MHz, governor - interactive.
little cores: min - 384 MHz, max - 1440 MHz, governor - interactive.
CPU Boost - disabled on all cores (I suppose that stock variant with "input boost frequency core 1 - 1248 MHz" was reason why all settings didnt stock on, so this option is disabled now)
CPU Hotplug
Thunderplug is enabled;
Min Cores screen off - 2;
Sampling Rate - 600;
Load Threshold - 60;
I get that I wanted. Now there isnt 6 cores online always. With this settings I didnt got noticeable lagging, and on small system load I have only 1 little and 1 big core online. Others are offline!
Will test this out, it should get some batery for device (SOT).

If you are rooted, you could flash one of the custom ROMS that has a custom kernel. You could change hotplugs, governors, etc. Or if you want to stay stock, there is also a custom kernel for that. Thunderplug takes several copies offline.

I am rooted, but want to stay on stock ROM. Some time ago I tried v4tk kernel, but had some problems with it - interactive governor disabled one big, and two little cores. Also I couldnt change max and min frequency. So whatever I did, I had one big core offline, but other one was always on ~1.2Ghz. It didnt go to 300MHz or to 1.8GHz.
So the main question for now - Is there some special governors for hexa-core phones? I see that in stock interactive governor when screen is on, all six cores always is online, so I am looking for other governor, that uses same type for agresive performance, but also that can disable big cores by it self. No drops in performance.
But thanks for answering this thread.

Sorry for bothering in your thread but I see you have some misconceptions about kernels. The governor is nothing more than a set of rules that the CPU follows and uses to decide when, how much and for how long to scale the FRECQUENCY.
What you are looking for is an HOTPLUG, which is the part of the kernel that tells the CPU to HOTPLUG( disconnect or connect) a number of cores, also contains parameters for when to do that, at which initial FRECQUENCY to HOTPLUG the core and also for how long to wait until disconnecting it.
I am using v4tk's kernel right now and I can confirm it works as a beauty. In version V5 (the latest for my XT1572) he even modified the Thunderbolt Hotpluging and adapted it to respect six cores little.Big configuration. In my experience with this HOTPLUG it keeps first little core and first Bigg core always on during screen on, then it gradually lights up second, third, forth little cores when needed. I didn't got to make him light up the second Big core in Kernel Auditorium, but I'm pretty sure it lights up when video is decoded or encoded.
I don't recommend you using the newly added MSN, it doesn't do much for me.
As for the governors ( you can select two: one for little cores and one for Big) I stay with stock Interactive and I haven't experienced bad frequency scalling.

Finally, big THANKS to you for explaining things!
Will try later v4tk's kernel to change HOTPLUG, but I had some bad experience - all settings that I changed didnt stick on, so after some seconds they lived their lives.
As we all know, the Snapdragon 810 processor in our OnePlus 2 phones is prone to overheat, especially during heavy tasks such as gaming. With the stock kernel (which probably most of you are using) this leads to the A57 cores being partially or fully shut down and the display - which generates additional heat - being dimmed in order for the phone to keep a healthy temperature (healthy for both its components and the hands that are holding it.) This, in turn, leads to lag when playing especially demanding games. Which in turn leads to a frustrated user.
With root access, it's possible to use custom kernels and/or custom thermal throttling profiles in order to (at least partially) circumvent these issues, by throttling the CPU frequency and/or limiting the number of active cores, using different schedulers and governors, and by applying thermal profiles that allow the phone to get hotter (in order to keep higher CPU frequencies for a longer duration).
Since I bought the OPT, I was playing a very power hungry game - Republique - which, at its highest graphics quality setting, pushes the phone to its limits. I quickly switched from the stock kernel to the Boeffla kernel and started experimenting with schedulers, governors, hotplugging settings, CPU/GPU frequencies and thermal profiles, but nothing I have done so far makes it possible to play the game for more than 15-20 minutes before some kind of throttling / heat control sets in and the game starts lagging.
I tried limiting both CPU clusters to only 2 cores while maintaining higher frequencies, I tried throttling the frequencies and keeping all 8 cores active, and I tried all kinds of solutions in-between with anything from 4-8 cores active and frequencies anywhere between 60% and 100%. I also tried the various thermal profiles that the kernel offers. But whatever I did, the game was either lagging right from the start, or running smoothly for about 15 minutes before the screen was dimmed and the CPU was throttled, leading to a laggy experience.
So my question is, what do you guys do to keep the OnePlus 2 from overheating during gaming, while at the same time maintaining a lag-free experience? I don't seem to get anywhere with anything I try, so I'd be extremely grateful for some useful input.

All the phones throttle while gaming. I use thermal extreme with boeffla kernel. And use 2 a53 at 1,3ghz and 2-4 a57 at 1,4ghz and I modified the throttle file and it underclock to 1,2ghz when it gets hot but it doesn't happen if you don't play longer than 30minutes and it doesn't lag either. You can leave stock settings but if course it will get hot quicker. Also with thermal hotplugged or something like that, I used it all cores online all the time at full speed and it doesn't throttle for a long time, so I don't know what overheating are you talking about. My nexus 5 throttle faster and disable 2 of 4 cores and leave the other 2 at half speed, and our processor overheats?. Oneplus throttle the device a lot because of the rumors, fortunately we can change that. Try what I said, cheers.

Thanks for the tip with thermal extreme! The implementation in the latest Boeffla kernel v1.1 beta1 seem to do a very good job of not letting the phone get too hot while at the same time not throttling the CPU too much. Today, the performance was stable for almost 30 minutes of gaming, and when I checked the CPU stats I saw that all cores were still active (2x A53 + 4x A57), and only throttled to 960 MHz. This still delivered enough performance. (I started the game with both CPU clusters at 1.2 GHz, so this also seemed to help with keeping the phone at an acceptable temperature. I'm sure it would've gotten much hotter much quicker at higher CPU frequencies.)
I have to admit though, I was playing inside in an unlit room and thus the screen wasn't at max. brightness. We'll see how it will perform during my next work break when I have to make the screen much brighter.

Does it throttle to 960mhz? for me never reach 1,2ghz. Playing real Racing for 30min it stays at 1,2ghz. And with thermal hotplugged (all cores enabled, all at stock freq gpu too) it doesnt throttle for 30 min, gpu only sometimes to 510mhz, i played 30 minutes and it didnt throttle, i dont know when it was going to throttle because i stop playing. But also, gaming with all cores and no throttling eats the battery.

I guess it throttled to 960 MHz because the game I'm currently playing (République) is pretty resource hungry.
